Combined with the functions of the one-piece Bluetooth headset: * the ability to receive and respond to incoming calls * wireless/ radio-frequency connectivity * long battery life.

Motorola Sports Headphone is one of the better wireless headsets. It's marketed as having HD speaker system. It's difficult to prove that it's actually "High Definition" but the dynamic range is incredible. Listening to streaming audio up to 256 kbps and mp3 at 320 was a pleasure.

The power of this device is in its drivers and its built in amplifier. So, if the music source is of lower quality, there's no way that the device will produce a HD sound, it can receive and replicate what is transmitted. The good news is that Bluetooth paired devices like a laptop or a smartphone usually have a built-in equalizer.
